arrayList hierarchy

Hyper_Mïko

Hi, i don't really know how to ask this on google :

I have multiple page (each page is a class and have one instance) on my application and every time i change the page where i am, i reset my arrayList where is stock all my Button

In each button i want to acces to the variable focus (if one button is focus other are unfocus)

for(int i = 0; i < button.size(); i++) button.get(i).focus = false;

i got the error : "the name "button" cannot be recognized"

i search a code like :

for(int i = 0; i < this.parent.size(); i++) this.parent.get(i).focus = false;

here parent is not a class name but the arrayList.

I don't know if i was clear, i'm newbie and my english is not really good.

Your question is not clear. Post your entire code, formatted correctly.

You said:

is stock all my Button

and then:

"the name "button" cannot be recognized"

... Button != button. Is your problem capitalization of the variable name? Can't tell without seeing your code..

buttons with s maybe...?

Sorry, but i can't post the entire code : i have 600 ligne in 4 page This first part is where i have my class

class Input {
  boolean hover, activ, focus;
  float posX, posY;
  float sizeX, sizeY;
  String label;
}
class Button extends Input{
  Button(String l) {
    posX = 0;
    posY = 0;
    sizeX = 230;
    sizeY = 75;
    label = l;
  }
  boolean interact() {
    float screenX = screenX(posX, posY);
    float screenY = screenY(posX, posY);
    if(mouseX > screenX-sizeX/2 && mouseX < screenX+sizeX/2 && mouseY > screenY-sizeY/2 && mouseY < screenY+sizeY/2 && !mousePressed) hover = true;
    if(mouseX < screenX-sizeX/2 || mouseX > screenX+sizeX/2 || mouseY < screenY-sizeY/2 || mouseY > screenY+sizeY/2) hover = false;
    if(hover && mousePressed) activ = true;
    if(activ && !mousePressed) {
       for(int i = 0; i < button.size(); i++) button.get(i).focus = false; //<== The issue is here : if i click on the button i turn for all focus to false and i turn the focus of this to true
      focus = true;
    }
    if(!hover || !mousePressed) activ = false;
    return focus;
  }
}</pre>

This second part is where i use my class

class Menu extends Page {
  ArrayList button;
  Menu() {
    button = new ArrayList();
  }
  void setup() {
    if(user.pseudo == null) button.add(new Button(350, "Se connecter"));
    else button.add(new Button(350, "Bonjour, "+user.pseudo));
    button.add(new Button(350, "Jouer"));
    button.add(new Button(350, "Option"));
    button.add(new Button(350, "Créer une carte"));
    if(user.pseudo == null) button.add(new Button(350, "Quitter"));
    else button.add(new Button(350, "Se déconnecter"));
  }
  void draw() {
    colors.fillInput(#000000, #303030, #00FFFF, #00C0C0);
    colors.strokeInput(#FFFFFF, #00FFFF, #000000, #000000);
    
    pushMatrix();
    int nbrBtn = 5;
    translate(0, -40*(nbrBtn-1));
    button.get(0).draw();
    translate(0, 80);
    button.get(1).draw();
    translate(0, 80);
    button.get(2).draw();
    translate(0, 80);
    button.get(3).draw();
    translate(0, 80);
    button.get(4).draw();
    popMatrix();
  }
  void interact() {
    pushMatrix();
    int nbrBtn = 5;
    translate(0, -40*(nbrBtn-1));
    if (user.pseudo == null) {
      if(button.get(0).interact()) {
        login = new Login();
        login.setup();
        nPage = 1;
      }
    }
    translate(0, 80);
    button.get(1).interact();
    translate(0, 80);
    button.get(2).interact();
    translate(0, 80);
    button.get(3).interact();
    translate(0, 80);
    if(user.pseudo == null) {if(button.get(4).interact()) exit();}
    else if(button.get(4).interact()) user.disconnect();
    popMatrix();
}

This third part is where i create and call my Page "menu"

Menu menu = new Menu();
void draw() {
  menu.interact();
  menu.process();
  menu.draw();
}

I think i give all you need.

The question was how too find the container of an arrayList... The answer is : we can't.

Thx for the time you give me.
